    42543 is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from Just as advertised After 12 years, it is hard to believe that I can buy the same mufflers for less than $100 a piece. Due to their sound and quality I had to buy them again for my 70 Chevelle SS.

    Rated 5 out of 5 by from Great Product. I have installed these series 40's on my Mopars for years. Love that throaty muscle car sound they produce and ease of installation. Inlet and outlet port sizing is spot on.

    Rated 5 out of 5 by from Flow master 40's I bought these Mufflers over a month ago and I'm very happy with the sound and the durability. I will be buying another set for my GTO in the near future. Good job Jegs!!

    Rated 4 out of 5 by from Good sound I really like the Flowmaster sound. Definitely has some drone at idle, but goes away when driving. Overall pleased with these mufflers.
